As I don't know the exact Tiger Sangha real story, it's hard to say the significance. But generally, if it's a story about a community or group, it might be significant in terms of the values they uphold, the relationships they form, and the impact they have on the local area or the people involved.
I'm not sure specifically which 'Tiger Sangha' you are referring to. There could be many things or groups named like that. It could be a local organization, a personal project name, or something else entirely. Without more context, it's difficult to tell the real story.
Hentai manga does have some popularity, but it's mostly within a small and specific audience. This is because it typically contains adult and often controversial themes that don't appeal to the general public.
The 'hinata nude streak comic' is likely to be unethical and potentially illegal. Comics like this are not in line with proper values and should be disregarded.
